ELECTRICAL FEELER ARRANGEMENT FOR WEAVING-LOOMS.

Specification of Letters Patent.

Patented Feb. 3, 1920.

Application filed August 25, 1919. Serial No. 319,729.

To all whom it may concern Be it known that I, HARRY TER KUILE, manufacturer, a subject of the Queen of the Netherlands, residing at Enschede, the Netherlands, have invented certain new and useful Improvements in Electrical Feeler Arrangements for Weaving-Looms, of which the following is a specification.

This invention relates to an electrical feeler arrangement for weaving looms and has for its object to feel in every position of the slay when the shuttle is in the shuttle box, that is to say nearly during the time that the crank shaft does a half rotation. a

A further object of my invention is to let the feeling take place in change box looms before or after the shuttle box has been changed which latter takes place when the slay is in the front position.

In the accompanying sheets of drawings which illustrate my invention:

Figure 1 is a view of the shuttle in front elevation;

Fig. 2 is the shuttle with shuttle box partially in plan view and partially in sectional vlew;

3 is the shuttle with the shuttle box ilp cross-sectional view on the line 33 of is illustrated in'the drawings, in the I shuttle 1 a metallic feeler 2 is applied, being a bended piece of metal, which is rotatable around a vertical metallic pin 12 which passes through the right end of the opening for the feeler. The feeler 2 is continually pressed against the side wall of the shuttle by means of a slight spring 3 in such a way that the cop is completely free from the spring when the shuttle moves, and that the feeler cannot occasion any trouble to" the yarn. Further a bow 5 is applied in the shuttle box 4. which shuttle box is made of wood or of any other insulating material, the bow 5 being at its upper part hingedly connected to a pin 6 (Fig. 3).

The bow 5 is continually pressed toward the inner side of the shuttle box 6. g. by

means of a spring 7. The bow 5 is placed in such a way that it presses against the feeler 2 when the shuttle is present in the shuttle box. As the pressure exerted by i the bow 5 is greater than that which is exerted by the spring 3, the feeler 2 will be pressed toward the cop in the shuttle, until it encounters a resistance from the cop itself.

. presses as soon as the shuttle arrives into the shuttle box.

In this way it is possible to obtain an electrical conduct through the shuttle between the'bow 5 and the bow 11. If this conduct is used as a part of an electrical circuit, which serves for operating different parts of the loom, the aim of the invention is reached.

If a bobbin is used to fasten the cop upon the spindle of the shuttle instead of fastening it directly upon this spindle, it is only necessary to adjust a metallic plate on this bobbin, which plate is electrically connected with the spindle or in any casewith the contact plate 10.

It is also possible to adjust a contact spring or a pin in the shuttle with which the feeler 2 comes into contact when the cop is sufficiently emptied.

7 Having fully described my invention, what I claim is:

In combination with a shuttle and its shuttle box, a conducting feeler pivotally mounted in one side of the shuttle, a spring to cause said feeler to be normally pressed against the side wall of the shuttle, a contact element on the shuttle and electrically connected with the spindle. a spring pressed contact element in the shuttle box and engagingthe contact element of the shuttle, and

a spring pressed bow arranged in the shuttle box and exerting pressure greater than that ofthe first named spring to press the feeler toward the cop and thereby close an electric circuit when the cop is sufiiciently emptied. In testimony whereof I afiix my signature in presence of two witnesses.
